Glenn Reynolds in the Washington Examiner on the lessons of McDonald and the actions that led to a pro-gun-rights ruling that was unthinkable in recent memory.
In little more than 15 years, we've seen an amazing turnaround on an issue where the "establishment" side had broad support from politicians (in both parties, really) and almost universal support from the media. Gun control now is nearly dead as an issue, and the "establishment" view that the Second Amendment didn't protect any sort of individual right, but merely a right of states to have national guards, did not get the support of a single Supreme Court justice.
So what's the lesson for today? It's that activism matters.
Now the issue on which activists differ from the establishment is the size of government. Politicians (in both parties, really) are pretty happy with big government. In this, they have the near-universal support of the media (now using covert e-mail lists to agree on how to slant their stories).
But if people care about shrinking government as much as gun rights activists care about protecting the Second Amendment, then this situation, too, can see a turnaround.
